Final answer:
The True/False statement about whether a customer must pay with a credit card over the phone for orders $100 or more cannot be universally confirmed without specific context, as payment policies vary by business.
Step-by-step explanation:
The question pertains to a policy regarding payment methods for certain order values. However, without further context or a specific store's policy provided, one cannot definitively state whether such a policy exists universally.
Generally, payment policies vary from business to business and are not dictated by the order value alone. It's possible that some businesses may require payment by credit card over the phone for orders of $100 or more, but this is not a standard practice applied to all transactions of this amount.
Therefore, the statement is not universally true or false without additional context.
